- This invention relates to gas mixers for internal combustion engines and has foran object to provide new and improved type of apparatus for commingling and inter-mixing heated gases from the exhaust with the incoming gasoline vapor before introducing into the'carbureter for mixing with the required charge of air.

A further object of the invention is to provide in a gas mixer communicating chambers through which successively the gasoline vapors pass and in the latter of which the vapors are intimately intermixed with hot gases from the exhaust manifold and from which latter chamber the gases so mixed pass to a carbureter,

A further object of the invention is to provide communicating, preferably approximately spherical, chambers through which gasoline passes successively, in the latter chamber being subjected to an agitator operated by the introduction of heated gases from the exhaust manifold under pressure to commingle with the passing gasoline vapors with a thorough intermixing produced by the agitator.

lVith these and other objects in view, the invention comprises certain novel parts, elements, units, combinations, construct-ions, in-v teractions and functions as disclosed in the drawings together with mechanical and functional equivalents thereof as will be hereinafter more fully described and claimed.

In the drawings: 1 a

Figure 1 is a view of the gas mixer in side elevation.

Figure 2 ,is a diametrical sectional view through the gas mixer taken on line 22 of Figure 1. c

Figure 3 is 'a transverse sectional view through the agitating chamber taken on line 33 of Figure 2.

Like characters of reference indicate corresponding parts throughout the several views. v a

The improved gas mixer which forms the subject matter of this application comprises chambers A and B, preferably though not necessarily approximately spherical. These chambers A and B'communicate with each other in any approved manner as by a conduit 10 which is formed through a threaded shank 11 which is formed upon the wall of one of the chambers, as the wall 12 of the chamber B. The wall of the other chamher, as the wall 13 of the chamber A, is screw threaded as, at 14, to shank 11.

engage on saidthreaded 1 The chambers -A and B .are respectively made up of walls of separable sections, the walls 12 and 13'having'already beenno'ted, the other sections12Tand 13 being connected with the sections '12 and 13 in any v approved manner as by formingfianges or cars '15 and employing screws orbolts 16 for holding the substantially semi-spherical seetions together. For the purpose of making.

gastight joints, gaskets 17 are employed;

The chamber-A is in communication, when .in use, with the source of gasoline supply as the vacuum tank and a pipe 18 is shown 1n the drawings for the purpose of conducting the gasoline from suchsource" to the chamber. A. It is to be understood that the relative lengthor size ofthis pipe, 18 and the connection 19 shown thereon are only illustrative and will be varied according to i chamber, while the chamber B is provided with an agitator. The agitator is in the form of a fan 21 which is mounted to rotate upon an axis substantially in alignment with the conduit 10. For'conve'nienc'e of mounting the agitator, a collar 22 is introduced into proper furrows in the sections 12 and 12 of the chamber B so that, when the sections 12 and 12 are'secured together by the bolts or screws 16, the collar 22 is held firmly in position. Cross pieces 23 are provided for holding a journal pin 24.

For the purpose of rota-ting' the agitator 21, an inlet 25 is provided normally in communication with the exhaust man fold, a

check valve 26 being provided to prevent back pressure from returning through, theexhaustmanifold to carry gases from the chamber Bto exhaust. For connecting with the carbureter, a'connection 27 is also provided, it being understood that the particu v lar type of connection both at 27 and at 26 forming a part of the check valve will vary as required by the. particular installation.

Also a collar 28 with wings 29 or other appropriate means for attaching the device to'the dash or other parts of a car or instalj chamber 1 through the tubing 18 or the equivalent into the chamber A is subjected to this, heat, in the chamber A and vaporized, passing thence through the conduit 10.into the chamber B. In this chamber B the vaporized gasoline from the chamber A is intermixed 'Withthe heated gases from the manifold introduced through the conduit 25, such gases by being introduced at the angle indicated at Figure l, rotating the agitator 21 to thoroughly in term x said exhaust gases and the gasoline vapor, which intermixed gases pass out- Wardlythrough the connection'27 to the carbureter Where they are mixed with the air in proper proportions 1n the usual Well known manner; 1

- lVhat I claim to be new is: u a I l. A fuel volatilizer comprising a primary constructed substantially as a sphere With polar conduits communicating (therewith, one of Which isadapted for con nection' to a carbureter, a mechanical agitator Within said chamber moving upon an axis coinciding With the pole of the sphere,

an inlet conduit for heated gases (3011111111111 eating with the chamber at a tangent and at an inclination to the equatorial plane, a-

second chamber communicating With the first mentioned chamber through one'of the polar conduits, and means to introduce liquid fuel into the last mentioned chamber;

I I 2. A fuel volatilizer comprising. a substantially spherical chamber having polar: con.-

duits, a tan locatedwithin the chamber With its axis coinciding with the pole androtat ing in a substantially equatorial plane, a secondary chamber communicating- With the first mentioned chamber through one of the I polar conduits, means to introduce a'liquid "fuel into the last mentioned chamber, means to introduce a heated into the firstmentionedchamber-at an inclination to the plane of the fan, andmeans communicating with the polar conduit oppositethe second mentioned chamber. to conduct the m xed gases toa carbureterl In testimony whereof I afiix my signature.
